Cannot e-file Schedule C

I Have TurboTax Deluxe for PC.  When trying to e-file my 2023 return, I get an error message that certain forms cannot be e-filed. I determined that the problem is Schedule C. I deleted the Schedule C and the program will allow an e-file. When I add back the Schedule C I get the error message again. I tried inputting Schedule C with income only and no expenses or business credit and still get the error message. When I again remove Schedule C the error message goes away and I can e-file. I realize that the IRS is not accepting returns until January 29th, but I wanted to resolve this issue early. I also noted that none of the forms associated with my Schedule are unavailable. This appears to be a coding issue with TurboTax for the 2023 filing. Has anyone else had this issue and are you aware if there will be an update forthcoming?
