My 1099 wasn't sent by the 31st. Should I wait until it shows up or just do them now? I have all my other w2s and 1099 documents ready to go.

I've never filed a 1099 so I'm asking before I make an uneducated decision.

Edit: I have informed mail delivery and it said the document is actually on the way today. Thanks for all the replies

Update::It's a 1099 NEC and my informed delivery said it should be here today, the 10th, and it never showed up.
