No one in a user community forum can know what all the IRS is doing with your 2018 return. Have you tried to talk to them using the steps provided above or by a phone number in your IRS letter?
Have you talked to the IRS Taxpayer Advocate Service for assistance? If so, you didn't mention it.
At the following IRS website, find the USA map and click on your state, and it will give you the number of your IRS Taxpayer Advocate.

Also see this article for more info on how the Taxpayer Advocate Service works::

If you don't get good assistance/results re: your 2018 return from the IRS and IRS Taxpayer Advocate Service, you could notify your Congressman's local district office to see if they can help you.
