My 1040 line 1 – doesn't match the W-2 info I entered, and references a ‘Sch 2704’. There is no schedule 2704 in my return package?

There is a form 8615 showing an amount on line 1 as $2704 (coincidence?) but I didn’t provide that number either.  And on  8615m it is an entered number, not calculated.  How will the IRS follow this if I can't?
