How to specify that my IRA distribution was both 5.5k of nondeductible 2016 contrib and 2k of rollover from 401k after tax

[Pantelis]

Hello
In 2016 I made a 5.5k non deductible contribution to IRA and transferred another 2k from a 401k after tax account. The 2k is gains only (moved the contributions to a roth IRA also), so I'm fine paying taxes there, but I can't tell turbo tax that. It seems to think I have to pay taxes on full 7.5k, or I can force it to think that 7.5 was the transfer with 5.5k cost, but that's not true either. Ideally I'd want 0 cost bases for the 2k and file 8606 for the 5.5k.

Turbo tax seems to only ask for non-deductible contribs from 2015 or earlier, but I started 2016 with 0 balance.
It seems clean cut case to me but I can't seem to figure it out!

Any guidance or help?

thanks

Regarding the $5.5k, you must enter your nondeductible 2016 traditional IRA contribution under Deductions & Credits

The gains distributed from your after-tax 401(k) account are before-tax amounts and do not add to your basis in traditional IRA contributions.  That makes the taxable amount of a $7.5k distribution or Roth conversion from your traditional IRA $2k taxable.

Thanks a lot!!!
I realize I was getting confused because I didn't see any questions for the 2016 (inline with reporting the 1099R), but jumping ahead to the deductions made everything add up correctly eventually!
