You "just filed" a 2018 W-2? Did you use the online program---which is ONLY for a 2019 tax return? If so, you made a mistake. Online cannot be used for 2018. If it somehow gets accepted, you are going to have to amend it later and pay back the refund.
If you get lucky and it is rejected, you can delete the 2018 W-2 from the return and use the account to prepare your 2019 return--which is what it is supposed to be used for.
Post back when you know if the return is accepted or rejected so we can tell you what to do next.
The way you were supposed to file 2018:
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.
