Where do I get my tax liability from 2018?

[RHG]

I had to get it from the copy I printed last year. I lost all turbotax files from my computer and turbotax had no past records even tho I have been using them for years.  Good Luck!

You can get a copy of your 2018 tax return from TurboTax.  Follow these steps to get a copy of your prior-year tax return.

Sign in to TurboTax making sure you're using the same TurboTax account (with the same username) as in prior years.

1. Select Documents from the navigation when it appears.
2. Use the drop-down menu at the top of the screen to choose the tax year you want and then select Download PDF.
