I didn’t file my last year W-2’s, I have 2 of them from last year. Do I have to enter those W-2s(from last year) with this years W-2?

Or do I file those separately from this years W-2?

You have to file those older w2 with a tax return for that year.  So if they are from 2018, you need to file a tax return for 2018 and a separate tax return for 2019.  For the 2018 return, your really late.  If you get a refund, no problem.  If you owe money, there will likely be penalties.

Every tax year's income has to be filed separately.   You cannot combine 2018 and 2019.  The online program is only for 2019--no other year.

Online preparation and e-filing for 2018 is permanently closed.

To file a return for a prior tax year

If you need to prepare a return for 2016, 2017, or 2018 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

Remember to prepare your state return as well—if you live in a state that has a state income tax.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.

Note:  The desktop software you need to prepare the prior year return must be installed/downloaded to a full PC or Mac.  It cannot be used on a mobile device.

If you are getting a refund, there is not a penalty for filing past the deadline.  If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.
