TT error - Blank Form associated to form 8606

I am reviewing by 1040 and supporting forms via the Print center.  I see a page called "Blank Form".  It has comments on from me relating to form 8606 and a basis change BUT I did not populate this form when entering data and I know by the comments that they related to a return from 4 years ago.   I checked last year's return and the same error didn't seem to be there.   Why has this happened and more importantly how do I delete the blank form?    I do have a 8606 in this year's return that that is showing as populated correctly.

 

Thank you Richard
