Trying to E-file amended 2019 return

I am trying to e-file an amended 2019 tax return.  I can get all the through the e-filing process until the system asks for a filing date.  When I input today's date, it says the date has to be between 1/1/2020 and 12/31/2020.  Does this need to be fixed? According to the IRs you should be able to efile an amended return
