My wife opened a Traditional IRA in late 2017, and then funded it with $5,500 after-tax (nondeductible) dollars in January 2018. We made sure to tell Vanguard that the contribution was for 2017.
We proceeded to fund the same traditional IRA with another $5,500 for tax year 2018.
We converted the entire Traditional IRA to a Roth IRA in 2018.
Box 1 of 1099-R form that Vanguard provided has $11,000 in it (which makes sense). When I put this into TurboTax though, it views it as an overcontribution (I think) and my refund numbers go down significantly both in Federal and in State. My federal number stays the same if I change Box 1 to $5,500.
Any ideas what I should do?
