This all sounds very tiresome. Do either of you remind her that she's now an adult and she also has to try and solve issues herself?
I have a (just) 20 year old, away at uni. She didn't want to work. However her course is not over demanding, and she has expensive tastes, she needs a job. We just put the reminder there that while we are happy to support her at uni, we are not happy to fund her going out 2 or 3 times a week while not working, so she needed something. She sulked a bit, then realised that she wanted the kind of social life she wanted, so went looking. She found a job, no she doesn't like it, but she likes what the money can do for her.
She needed a dentist appointment. She asked me to ring, as she doesn't like making those calls. I reminded her that I was at work, busier than her at that moment, and as she was almost 20, they probably wouldn't accept me calling anyway. She realised she needed to crack on, and did it.
The point I'm trying to make is at that age, I think that they would quite happily let you do everything for them. But what good is it going to do? That's not to say don't help them, but surely you have boundaries. For example the job hunting, you went researching, she couldn't be bothered. Why are you researching, not her? If that was me, I would be telling her that if she found some things she liked the look of, then I would happily work with her to look through her CV and help write a covering letter. But how is she supposed to actually do the job if she's not even having to take the stress of looking for it?
As for the furniture, I think I would point out that it takes years of work before a house is exactly to your taste, so if it was me, I would buy something cheap and cheerful, until I could save up for the right one, and that life is a lot happier with a sofa to sit on with a friend. But, at the same time, I would realise that she is an adult, so if she would rather go without than have the perfect one, that's her decision to make, and not one that makes you a bad parent, she is an adult with enough of a brain and enough money to make that choice.
