If I have taxes from 2018 that I haven’t filed yet do I have to file them separately from 2019? Or can I do them all at the same time on the app???

Tax returns must be filed separately.  The TurboTax online  editions are Only for tax year 2019

To complete and file a 2018 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the 2018 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2018 tax return can only be printed and mailed, it cannot be e-filed.

You would file them separate & you cannot use the Online version.

For tax years 2018, 2017, or 2016

You'll need to purchase and download the TurboTax software for PC or Mac as TurboTax Online and the mobile app are only available for the current tax year.

After installing the software, open it and follow the onscreen instructions.

Prior year returns must be paper-filed, as e-filing is no longer available. We'll walk you through that process when you get to the File section in the software.
