Should I file a new amended return (2018) if my existing return isn't showing up as being received in the IRS website after 18 weeks?

Others have asked similar questions but my  tracking showed it was received on July 28, 2020 and I would at least hope it is showing up in the "Where's My Amended Return" site on the IRS Website, even with Covid 19 delays. Is it time to simply file it again?
