I made two huge mistakes but already e-filed and it was accepted.

I thought my last unemployment was received in 2020. After I filed I get a w2 for $16,000 worth of unemployment.  And a side job I have they gave me a w2 showing just $1,200 in earnings. Then after I filed I get one in the the mail showing $5,000 I. Earnings.  Anyways, I assume this screw up will delay everything months before I can try to fix all this?  Any suggestions?
