Return not acknowledged

I e-filed my Federal 2021 tax return with Turbotax. I am retired and the return calculated  zero payment due and zero refund due. The return was rejected because I had not entered my special security code (Turbotax does not do a good job of telling you when and where to enter that code.) So I revised my return with the code and Turbotax would not submit the return. Thoroughly frustrated and not finding any help on this issue from Turbotax, I mailed may return by USPS Priority Mail; it was received at the IRS in KANSAS CITY MO on March 14, 2022.  I still not have received any acknowledgement of receipt. What should I do? 

 

Turbotax would not e-file my site return because of a system error that does not recognize the lot number of the home I own, so in frustration I sent a hard copy of my state return with not taxes or refunds due. It was received at the State Treasurer Box in Trenton on March 14, 2022 but I have not received  any acknowledgement of receipt. What should I do? 

 

BTW, IRS Service Centers in my area don't even answer the phone, and I can't find a customer service phone number for Intuit or Turbotax.
