Retirement tax questions

The code in box 7 of my 1099R  is a 7. 
on other codes. 
I’m over 59 1/2 

 

What confuses me is the next TurboTax screen asking:

Where is your distribution from for Michigan information? 

 

M - Military Pension

G - Qualified Government or SS

C - Current year conversion from a traditional IRA to a Roth IRA

P - other qualified IRA distributions 

N - Pension/IRA distribution received before retirement age/ None of the above  


if I choose N; State of MI taxes my Conversion; 

if I chose C; State of MI doesn’t tax it.
