I was doing some research on how the 3.8% tax on investment income would impact me. it got me to looking at my 2018 taxes. I see something I don't understand in regards to my backdoor roth. I can't download the software. Trying to see if i made a mistake on my backdoor roth. Can anyone help?

On my 1040A:

Line 4a: Shows 5,500

Line 4b: Shows 0

Line 6 however, shows a value that includes line 4a. So, it appears my IRA got input in as taxable income.

My form 8606 15c shows taxable amount of 0, as does line 18

Did i pay taxes i shouldn't have?

I assume that you mean Form 1040. There was no Form 1040A in 2018.

Line 6 is the sum of lines 1, 2b, 3b, 4b, 5b and Schedule 1 line 22. The amount from Schedule 1 line 2 should be present next to line 6, but check Schedule 1 anyway. If you used TurboTax to prepare your 2018 tax return, it's doubtful that line 6 would show anything other than this sum unless you used an override to enter a different value on line 6, preventing you from e-filing.

@craigin805 suggest going back and checking the math again. Line 4b is the taxable amount and you state that was zero. The right hand column are the taxable amounts so I am hard-pressed to understand how Line 4a could be part of Line 6. are you sure?
