Any accountants out there?! Please can you explain about tax returns and NIC payments?!

I've just got my tax calculation but I can't figure out if the Class 4 and Class 2 NIC payments are included, or whether they need to be paid in addition to the "Total tax" amount in box 1 of the tax calculation summary.

So if it says, for example:
Total tax £2,000
Class 4 NICs due £700
Class 2 NICs due £200,

Is the total amount I owe £2,000, or £2,000 + £700 + £200?

Thanks for any light that anyone can shed!

Sorry, thought I'd included that info but forgot in my haste!
