How do I get to my 2018 tax returns so I can print them. I have not filed yet but I don't want to file them at this time

You can print your returns--you need to pay your TurboTax fees first, though.

Using the online turbotax; can you print before filing?

Again--you must pay your TurboTax fees before you can print when you are using online TurboTax.  Pay your fees, then you may print out your returns and mail them when you choose to mail them.
