After you file

NO!!!!!   Wait until you have all of your W-2's.   They all have to be on the same tax return.   Employers have until February 1 to issue them.  The IRS is not accepting 2020 returns until February 12.  So you have time to get all of the W-2's and file correctly.   If you file without all of your income on the same tax return you get to spend months amending the tax returns. It takes 4-6 months for the IRS to process an amended return when you mess it up the first time.

Every 2020 W-2 that you received must be reported on your 2020 tax return, even if they are for small amounts.  Remember that each one of those W-2’s has your Social Security number on it, and that income was reported to the IRS by the employer.  You do not want to get in trouble with the IRS for under-reporting your income.

ALL of your W-2’s must be entered on the SAME tax return. 

Go to Federal>Wages & Income to enter a W-2.

After you enter the first one, you click Add Another W-2.

W-2's come from your employer, and they have until February 1 to issue it.  Some employers allow you to import the W-2 through the software, but for security reasons you still need information from the actual W-2 to import it.  You might need to phone, drop in, email and/or snail mail an old employer to make sure they know where to send your W-2.

And….SAVE YOUR OWN W-2!  TURBOTAX DOES NOT SAVE IT FOR YOU.  TurboTax will not have a copy of it in your account and will not have an image even if you snapped a photo.  It is up to you to save it for your own records as stated on the back of the W-2.
