After you file

I am in the same boat. I initially had both my fed and md filing rejected because of an issue in TT. I refilled late (or early the next day) and both were accepted. So my MD was accepted on 1/26/203.

But the Maryland website says that it is still not processed. Just checked again.  

 

And of course, I waited on the phone for a long long time and then gave up trying to speak to anyone.
