How do I delete previous return that I didn't file? It's wrong and it affects this year.

Here’s a trick to delete it.  But it will clear out 2017 too so you have to start over.

Go to Tools on left > Transfer last year’s TurboTax return from your computer > Continue > Continue without Transferring

Open Turbo Tax.  Top Left is File, Forms, etc.  Open Forms.  At the bottom of the page you will see the choice to "Delete".  Choose the forms you wish to delete.  Hope this helps.

That is only for the Desktop program.  Not the Online versions.
