Help with Backdoor Roth Conversion and form 8606

TomDx — Mon, 14 Apr 2025 17:01:26 GMT

Can someone provide some help?....

This is my 1099-R from Vanguard...

1 Gross Distribution: 6,298,87

2 Taxable Amount: 6,298.87

2a Taxable Amount Not Determined X

Total Distribution X

7 Distribution Code(s) 2

IRA/SEP/SIMPLE X

16 State Distribution 6,298.87

On the 1040, both lines 4a & 4b are 6,300

This conversion is all post-tax and there is no balance in my traditional,

yet TurboTax is calculating Tax on the 1099-R and it shouldn't.

Thanks!

You entered the 1099-R but are missing the 8606 with the basis that has already been taxed. Once you enter the basis, it won't be taxable.

You need to delete the 1099-R, enter the 8606 or the contribution that isn't deductible, and then re-enter the 1099-R.

Good catch!
