I just called Tech Support about efiling 2018 and 2019... and was offered a link to our community! The Rep said he didn't know anything about efiling 2018 and 2019, but you all would. Is it really true that those years cannot now be efiled? I followed the instructions. Here is the 2019 error message:

"The Intuit Electronic Filing System is having difficulty recognizing the data you are sending. First make sure your product is up to date. Then open the return and run Final Review. Save the return and try sending it again. If you still cannot transmit the return please contact technical support for assistance. - The Electronic Filing Center is closed for the 2019 Tax filing season. - Please file your return(s) through the mail."
