ROTH contribution Logic Error

[FBarbara]

When I enter a ROTH contribution, for which I should owe taxes, my total tax due decreases. If anything, it should increase.  Is the software working correctly or am I potentially doing something wrong?  It seems to be interpreting that contribution as a deductible contribution or something else is happening.

When you enter a Roth contribution there is no tax. why do you think you owe tax?

You may get a credit on Form 8880; this increases your refund.

Sorry. I was a little confused between a Roth Conversion and a Roth contribution. 
I think I got it now. Thanks.
