Oh no. You cannot "fix" the year. You have used the online program that is ONLY for 2018 to prepare a 2017 return. That is a HUGE mistake. You cannot file it. You need to clear it out.

Each tax year has software written for the specific tax laws in effect for the tax year. You cannot use a different year's software for your 2017 return. The software years cannot be changed or updated. You can ONLY use 2017 software.
Online preparation and e-filing for 2017 is permanently closed.
To file a return for a prior tax year
If you need to prepare a return for 2015, 2016, or 2017 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.
