efiled 1099 nec forms and still reading processing! for 24 hours! Is there an issue?

Sometimes it takes a bit for those to be accepted. The IRS is getting backlogged with submissions.

I'm having the same problem. What does "takes a bit" mean?

The IRS usually takes 1 to 3 days to accept e-filed 1099s. However, processing might be slower due to the high volume around the January 31 deadline. Your forms are considered timely filed if they are in the processing stage.
