Help, I need to file by mail this years due to having to fill out a 4852. I have already done this, all I need to do is print- it's not letting me until 2/25. Why?

Why is it not letting me print out the progress I have already started? There is not one to talk to. I need to understand. It says avail to file by mail on 2/25/21, i started this return last weekend.
