I had the same issue the day of filing 7/15/2020 at 11:59pm with turbotax home and biz, I tried to contact customer support and its a very complicated process, where you have to call them. Very easy to get a hold of sales or buy their products, but if you need help its difficult, you can't even leave a complaint, this is the only forum I see for that, not even sure they will read this.
I am very disappointed that this problem has been around for so long (months) and they haven't fixed it. I have been using turbotax for 20+ years, I haven't had any problems like this but I will definitely be looking at their competitors for 2021. Lucky I have a PC and it didn't have the same issue and I was able to efile 40 mins late, I hope I don't pay a late fee.
