You asked: "How can I get my taxes signed at the bottom when I've already filed them? It shows accepted my my download shows no signature for my husband or I"
That's normal. Efiling uses an electronic signature. If you efiled a joint return, the software would have asked both you and your husband to each sign the return electronically on a page that asked you to enter a 5-digit Self-Select PIN and sign with your birthdate and "today's date." When efiling, the vast majority of people have no paperwork that needs signing. It wouldn't have let you efile without going through the electronic-signing screens.
If you want your paper copy to show hard signatures, you can each sign it manually in the signature section. But that would be just for your records. Do NOT mail it in. See my next comment below.
