Question about Overtime

After running smart check to finalize and submit our taxes, I am getting an error about overtime that the value cannot be more than 1/3 of the total of the W-2 box 1 (wages) minus W-2 box 7 (social security). This particular W-2 was a onetime side gig my husband did for a union that started at overtime because it was either a holiday or after midnight (can't remember the details). Box 1 is 2594.04 and box 14 (OT) is 1120.33. How do I resolve this so it was allow me to submit?
