2020 Refund.

I filed our 2020 taxes via TurboTax on April 6th, 2021. I then amended that filing on April 28,2021 via TurboTax when new tax data became available.  Then, I filed another amended return on August 31, 2021 when additional tax data became available and again this was done via TurboTax.  Refund owed to us as of 8-31-2021 amendment is $2862.  IRS has not issued the refund or acknowledged the track record.  What do I do now?
