Deductions & credits

I need help with this. I used the Deluxe. My wife and I both contribute our after tax money to ROTH IRA (we wrote checks to fund) since 2016.  I read elsewhere that I may not have to enter that in my tax return but TT has it asked. I believe TT got me wrong as the questions asked were too confusing. In the end, I saw my 2019 IRA information worksheets and prior has lines 7 ( Basis in IRA Conversions)  & Line 9 Conversion basis carryover as of 12/31/2029) filled with $6,500 for my spouse column & also Lines 23, 51 & 52 filled.  There were no entry  on Line 33 (Regular Roth IRA contribution). Does that mean, a mistake was made meaning my spouse made a conversion of $6,500 from her pre-tax IRA and the $6,500 was added to our AGI for 2019 and we got extra tax. I just found out that when doing my 2020 tax the same way; as soon as I entered $7000 ROTH contribution, we tax number increases right away. Thanks
