You'll need to provide more information. For self-employed/contract work, such income used to be reported on a 1099-MISC in box 7, but that was replaced with the new form 1099-NEC for 2020. So it would depend on what happened. Did they report the same income twice, once on the old form and once on the new form? Or did they report different income streams differently? Did they report something else in a different box of the 1099-MISC? If she is a regular employee and receives a W-2, then all her income from that employer must be reported on the W-2, even bonuses and prizes.
