8606 Non Deductible IRA to Roth Conversion

I converted 8606 Non-deductible IRA to Roth IRA in 2020.  In the IRA information worksheet, Part I, Traditional IRA Basis and Value, line 1 and 2 are correctly tracked by TurboTax.  Line 3, Basis carryover as of 12/31/2020 is only about 44% of the amount of line 2, YE value on 12/31/2020.  Shouldn't line 3 equals line 2, since no conversion or withdraw had been done previously.  Taxes were paid for line 2 amount and should be the cost basis to calculate taxable amount (i.e. investment earnings) in the conversion.  This caused the overstatement of IRA distribution taxable amount by 56%.  Please help.  Thanks.

Those calculations are done on the 8606 form.     The carry-forward basis will be on the 8606 line 14.

Per @macuser_22:

 

"This so-called “back-door Roth” method ONLY works if you have NO OTHER Traditional IRA accounts.  If you do, then the non-deductible part must be spread over ALL accounts and cannot be withdrawn by itself.  Only if you started with NO Traditional, SEP & SIMPLE IRA and ended up with a zero amount in ALL Traditional, SEP & SIMPLE IRA accounts will this Roth conversion not be taxable."
