I filed my tax return days ago thinking I'd contribute $6.5k after-tax money to traditional IRA for year 2023 before the April 15 deadline but just learned that my deposit wouldn't reach the account until after April 15. So in fact I ended up making no nondeductible contribution at all for 2023. Since I already reported that $6.5k on 8606 along with my 2023 tax return, I wonder if I need to amend a 8606 to change this amount to 0 and correct the total basis for IRA? And if I do need to amend, should I wait until I receive my tax refund?
I tried to amend the return in Turbo Tax but it doesn't allow me to generate a new 8606 since the new form would contain all 0s. IRS also doesn't recommend amending a return with 1040X if nothing on the original1040 changes but another post here mentioned that you cannot amend 8606 by itself without filing 1040X. Hence I'm confused what to do next. Appreciate any guidance!
