How can i resend the taxes 2018 electronicaly on irs

No.  E-filing for 2018 has been permanently closed since October 2019.  The only way to file a 2018 tax return is to print it, sign it 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.

You can no longer e-file your 2018 tax return after 10/15/2019.

To file your 2018 tax return, you have to print and mail it to the IRS.

You would never resend a tax return you would have to amend a tax return.  The 2018 return you first sent is already filed for 2018.  So if you are fixing a return you would have to amend the return which is a different form.

Hope this helps you out!
