Self Assessment for Child Benefit - HOW to pay?

[sellotape12]

I'm going round in circles on the HMRC site. I need to pay the Higher Income Child Benefit charge for 23-24 as I took a few months benefit without realising my pay had gone over the amount. I cannot see where to file this return.
There's a button the homepage saying Do you need to pay the High Income Child Benefit Charge? then it just gives advice, no through button. When I click on my Self Assessment page it says
Self Assessment
Self Assessment Unique Taxpayer Reference (UTR): 123456
Your returns

You have filed your return for tax year 2023 to 2024.
...and when I click on 'amend', I get this message:
Submitted Return
As the HMRC service was not used to file a tax return for this year, you can't use the service to amend that return. Self Assessment Helpline for further assistance.

Am I being thick? I've spent 42 mins online getting nowhere.

I've just paid my tax. I submitted the return last night, but the amount I owe in tax wasn't showing under the payment link - apparently that can take a few days to update.

So I had to follow the payment link (I agree it can be a bit confusing and circular), and while it is telling me they owe me £25 and I have nothing to pay (as that is the non - updated figure), I had to manually insert the tax I know I need to pay and I could pay that.

HMRC really don't make it straightforward and easy. Our accountant has over 40 years experience with all accounts, taxes, HMRC etc and he finds it confusing. Its not us, its HMRC.

Good luck paying your taxes today everyone.

Tried phoning twice and every path is a dead end. It’s all pre-recorded information and zero way to get to an agent.

@sellotape12 today is the deadline I suspect it'll be nigh on impossible to get through.

I just don’t understand it. It says that I’ve done the Self Assessment return and I owed them £1.50 or something but I know I owe them about £700. There are just dead ends everywhere. I’ve spent hours on the website, hours on the phone. The website tells me to ring a helpline and then the helpline cuts you off.

I mean, it's 31st January, literally the busiest day in the SA calendar. I wouldn't be surprised that you can't get through on the phone today.

You've literally left it until the deadline day, as others have said you have very little chance of speaking to anyone, and from tomorrow it will be classed as a late return so prepare yourself for a fine as well. Is the £700 you think you owe definitely not this tax year but last tax year?
