If I go for the option to amended the previous return and mark the IRA contribution nondeductible (year of 2022), do I have to wait until the amended return finished processing and accepted (it usually take a half year plus), before I can file for this year return (2023)? Or I can just file 2023 and take it as nondeductible IRA conversion (or leave a note somewhere saying I'm amending 2022)?
Also it would be a interest charge for the deductible IRA changed to nondeductible IRA for the 2022?
Thanks so much !
