IRS says that I did not report an annuity income on my 2017 return that I show on my TT Tax file as reported. is it possible the TT program erred in calculating income

Where does it show up?  Which line 15 or 16?  If it's on the wrong line the IRS will miss it and say you didn't report it.  Or you got the wrong taxable amount on the "b" line.
