You cannot combine them if that is what you mean. Each year must be prepared and filed separately. The current online software is only for 2018 returns.

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 and/or your state received the return.
