Give 3rd party online access to tax return

Who?  Someone helping you fill out your return?  You would have to give them your user id and password.  Or save the pdf file to give them.

Be careful!   We don't know what you are doing and why, so be sure you don't become a victim.   Whoever has access to your online account and/or tax return will also have access to any bank account info therein and possible credit/debit card information, as well as all of your personal info (SSN, DOB, address, etc.)

Thank you.  Some on line mortgage lenders now require access to your tax return and can get into Intuit but not the return

Never heard of that.  Sounds sketchy and fishy.  Doesn't sound right.  Don't allow anyone to access your return.
