Deductions & credits

I got the same exact codes 

766,766,768 on 04/15/22 Then 810,811,971  on 02/21/22 then 424 was on 2/21/22 but now disappeared and it now says 420 for 02/04/22. Wmr states the path act and should have refund by the first week in March. Called advocate we I’m in middle of closing for a house which is expecting my tax refund to show I have a savings and moving money or the underwriter can deny the whole deal . So I finally was able to talk to an agent and told them of my horror story the last two years of waiting months and months for our refunds . She said a notice was sent 02/04/22 my refund was accepted 02/01/22 . I asked her if she knew what the notice was  and so she looked up a sample letter after a couple times saying it prolly had to do with the path act and the. Notice is prolly asking for proof of eic and ctc . Should I be worried this turned into a audit and that I’ll be waiting months for my refund ? I can’t afford not to get my taxes back my the beginning of March :( the agent referred me the advocate bc of my situation but I’m praying this won’t be a complication :( This is for the 2021 tax year !
