After you file

I have filed my tax return on 01/26/2020. I`ve red a notice at the end says that the e-file is not available and it will be available in February so I took the other option (mailing) and I didn`t know I have to print and fill the documents then send them by mail. I didnt print anything yet. I need an advice, should I wait till February then amend to e-file (recommended in turbotax) ? Go to H & R Block and amend to e-file which will cost me more money, or I should download turbotax CD and work on it ? I guess I should wait till February. I need your advice please.

Thanks in advance.
