If your 2018 return was rejected and you did not follow up and fix it and re-file or print, sign and mail it instead, then no, it has never been filed at all. You can still mail it. E-filing is closed 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/state received the return.
