I'm trying to print/save documents that TurboTax says I need to mail to complete my return but I'm getting,TurboTax is experiencing a temporary problem printing returns.

when TurboTax tells you to mail Form 8949, that does not mean the e-Filed Form 8949.

It means your additional Form 8949 showing itemized transaction details.

IRS requires details of your SELL transactions to be supplied on some Form 8949 (e-Filed or mailed in),
or on your other forms (e.g. consolidated 1099-B or spreadsheet) which have the same information and in the same manner as Form 8949.

it is meaningless to mail a copy of a form that you already e-Filed unless IRS asks for it later.
