It seems like either something got mixed up between the sale of the primary home and the sale of the second home, or you got confused looking at Form 8949. I would think that the EL codes would go with the sale of your primary home, not the second home. Are both sales on the same Form 8949? Are the descriptions of the properties sufficiently clear, and sufficiently different, that you are certain of which one you are looking at?
Did you enter the sales in the Step-by-Step interview or in forms mode? Did you enter the sale of the primary home in the "Sale of Home" section and the sale of the second home in the "Stocks, Cryptocurrency, Mutual Funds, Bonds, Other" section?
Forms mode can be complicated and error-prone. If you entered either sale in forms mode, I would suggest that you delete it and re-enter it in the Step-by-Step interview. If you can't find the problem, delete both sales completely and enter them all over again from scratch, being very careful to keep in mind which one you are entering. Make all the entries for one sale, then all the entries for the other sale. Don't jump back and forth between them.
