I found this thread a few weeks ago when searching for answers to my own (VERY) similar situation except I am not military.
I followed the recommended steps shown in this thread (Thank you Intuit) and was on the phone with a REAL PERSON with the IRS for over an hour, after holding to just be connected to a person for about 2 hours.
Like you I had received 2 letters last year, both telling me I needed to wait for them. Both letters stated there was nothing I needed to do and that they had 60 days to get back to me. I never heard another peep after July of 2019! Last month (February) the person I spoke with said I needed to contact AQC (Automated Questionable Credit) to verify some info. I spoke with a representative at AQC the next morning and was told I needed to verify some of my income and to either mail or fax the documents. I faxed them!! The person at AQC also notified me that my 2020 returns have an issue and I will have to verify my IDENTITY but, that I must wait until they send me a letter stating what is needed. It has been nearly a month since I spoke with someone & faxed my needed documents for 2019 and I have not received anything in return as of yet. Also to note that I filed my 2020 taxes the first week of February. This is beyond frustrating as my stimulus payments are also held up with this!! I am wondering if you made any progress?
