After you file

Ok I been using turbo tax since 2017 and never experienced this problem. I'm currently trying to file my taxes. I'm at the end and I'm trying to pay using my tax refund like I have always done. Unfortunately it will not allow me to and it's saying that I do not federal tax return but TT allows me to use my debit card to file. I don't have anything showing that I owe currently or ever. Very frustrated and confused. I DID look at FAQs but I haven't seen any that pertain to me.
