Thank you @DianeW777 ! I got the idea on where to check IRA deductible, but a follow-up question:
what should I do if I did a traditional IRA conversion to Roth in 2019 tax year but forget to report it correctly? (and I'm not 59yrs old yet)? Should I file a tax amend for tax year 2019 now, otherwise will be a big penalty later down the years? (though the traditional IRA contribution was likely after-tax, that I need to double check from previous tax files).
