We filed through mailing. I need to check if the name is included as either primary, secondary, or dependent.

You said "need to check",  so are you just asking how to download/print a copy of your 2018 return you prepared in Online TurboTax?    Primary and secondary refer to spouses 1 and 2.

 

To download/print your return, log in and at the Tax Home go to the section "Your Tax Returns & Documents".  Choose tax year 2018, then the link "download/print the PDF."

 

If you need to amend the online 2018 return, here's how:
