I completed an individual 2019 return in early December, with several states attached, and attempted to e-file it then.    It was rejected on the grounds that:

"The IRS and states have temporarily stopped accepting transmissions of TY19 individual e-filings.  The IRS and states will not accept transmissions of 2019 individual e-file submissions until January"

I have attempted follow-up filings on January 5,  January 12, and Jan 19 for this client all with the same message.  Does anyone know of when such 2019 returns may be e-filed or what an alternative may be?
