I AM filling my 2019 w-2 but I also have last yrs w-2

@ pbomm12 asked:  "I am filing my 2019 W-2, but I also have last year's W-2 from 2018 I haven't filled on too can I file with this yrs?"

NO.  You cannot report 2018 income on a 2019 return.   2018 income from your 2018 W-2 would be reported on a 2018 return. 

NOTE:  When you try to efile your 2019 return, it will ask you to verify with your 2018 AGI.  If you did not file a 2018 return at all last year, then you would enter a 2018 AGI of 0.  TurboTax may ask you if you filed a return in 2018.   If you didn't file one and say no, then it may enter the 2018 AGI of 0 for you in the background.

Did you file a 2018 return at all last year?   If you did, then it would take a formal amended 2018 return to add the 2018 W-2.    If you didn't file a 2018 return at all last year,  it cannot be prepared online (which is only for 2019).  The 2018 return has to be prepared in the 2018 desktop software (CD/download).   And it cannot be efiled.  It has to be printed, signed, dated, and mailed.

You can purchase 2018 desktop software as a download at this page and install it on your computer:

It's a good idea to mail by a method that has tracking, such as certified mail, priority mail, etc.

If you have both Federal and state returns, you need to mail each one separately to its respective tax agency. 

If you are due a Federal refund, it takes about 6 weeks for the IRS to process a mailed return and deliver the refund.

Or did you already start a 2018 return online prior to the 2018 online shutdown, and want to finish that one without starting over?  If so, you can download the *.tax2018 data file from your account and finish it in the 2018 desktop software.    If you already paid for your product previously, TurboTax Support should furnish you the software.

OR another option is to download the 2018 forms and instructions for free from the IRS website and fill them out manually.
