No IRA deduction for Roth IRA contribution

[novembergalsal]

Turbotax is not giving me any deduction for Roth IRA contribution.  According to my research, all $5500 should be deductible because my MAGI is less than $184000 and I made no other contributions to a retirement plan (though my husband did).  We are married filing jointly.  Any explanation?

Your research is incorrect. There is not now, nor has there ever been a deduction for a ROTH IRA contribution. That is one of the major differences between a Traditional IRA and a ROTH IRA.

You can find proof of that in IRS Publication 590-A at this link:
