Traditional IRA

I have a partnership with my wife. She does not share in the profits, only I do.  She has a full tie job where she is coved by a 401K plan at work.  I contribute each year to my SEP based on my earnings.  I always have done my own taxes on Turbo Tax but this yer I had an odd situation with my Partnership and took it to a tax preparer.  I decided to have them prepare my personal too. Our combined income is $174,000 with her W2 and my earnings from the partnership.  Our AGI is $153,700. My wife contributed $6500 to her Traditional IRA and I am now being told she cannot take contribute that much because of our income.  I was also told she has to remove it or I we will pay a penalty.  Can you tell me if this is correct?  I do not understand why.
