Please explain what you mean by "re-file." Do you mean your 2018 return was rejected and you need to file it? You cannot e-file it now since e-filing is permanently closed for 2018 returns. Depending on why it was rejected (and the rejection email tells you why) you might need to change something on it before you can file it, or you might just need to print, sign and mail it now. If it was rejected for AGI, then it does not matter, and you can just print it, sign it and mail it now.
But if it was rejected for some reason that will require changing anything, you will have to download desktop software to a full PC or Mac in order to make any changes before you can print and mail it.

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.
