I found the Q&A for this question:
https://ttlc.intuit.com/turbotax-support/en-us/help-article/small-business-processes/access-return-e-filed-printed/L4lXubpQ1_US_en_US?uid=ls8bh9zw
This is my situation. I printed, but I wasn't really done. I need to go back and correct some numbers, and then I want to e-file. Similar to the question asked and answered above.
However, the instructions given in the answer I quoted did not work. After I clicked "Add a State", I was not back in my return. I was taken to a screen where there was a button that said "Get Started". Then when I clicked on "Get Started", it told me "Not available until February 15".
