I did what others have done - since TT will not let you delete the WA state return once it's completed and we were not eligible for the WFTC, I just ignored it, selected E-File Federal return and selected "Do Not" E-File state return.
I don't plan to mail in a blank WA state return so I'm ignoring anything to do with the WA State part. It didn't even print anything when I printed the tax returns for my records. Federal return was E-Filed successfully. Hope that helps anyone who is stuck on this.
