I have leukemia need 2019 tax. Return to get help with medication . please send to my email .

Your return cannot be emailed to you.  You can print a copy of your 2019 return.  The tax return will show the income you reported to the IRS on it.  Not sure you who have to prove income to, but a copy of a W-2 would be better.  Did you save your own W-2?  If not, you should get another copy of your W-2 from the employer.

I NEED A COPY OF MY W-2  (or 1099)

TurboTax does not have a copy of your W-2—the Wage & Tax Statement—issued to you by your employer, (nor does TurboTax have copies of your 1099’s).   You should always save those documents for your own records. You could ask the employer(s) for copies or you can get a copy from Social Security (for a fee of $86).

If you saved a pdf of your completed tax return, the worksheets will show the W-2 information you entered, but not the actual W-2.

You can get a wage and income transcript from the IRS:  It will not show the actual W-2, 1099’s, etc, but will show the income information the IRS received.  It will not, however, show your state information. It will only show the federal information.
