How can I show that the IRS corrected my 2021 tax year refund after I efiled? Now I need to amend the return but the program assumes I received the original refund amount.

I efiled with Turbotax for 2021 tax year showing refund of $5,610.  The IRS sent a letter correcting the refund to $2,810 and that is what I actually received.  Now I need to amend the return but the refund amount calculated is $2800 greater than the correct amount.  How can I report in TT that the refund was less?  Can I add the $2,800 as a tax payment somewhere?

Then do I need to start my 2022 return over to pick up the changes?

Thanks, Cindy
