I need to have a filing of my taxes for 2016 to 2018. And I need it by this Mon, the 6th. I thought I filled the info out correctly but it will not file via turbotax

The TurboTax online editions are Only for tax year 2019.

To complete and file a prior year tax return (2016 thru 2018) using TurboTax you would need to purchase, download and install on a personal computer, Win or Mac, one of the desktop editions for each year needed from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A prior year tax return can only be printed and mailed, it cannot be e-filed.  When mailing multiple tax years use separate envelopes for each tax year.

If they need to be registered as filed on Monday you can take 2 copies to a local IRS office and hand one in & get the other one stamped accepted for proof of filing.
