I have the same codes my 150 code has a date of 3-9 with the amounts of 0.00 my codes 806 776 and 768 have a date of April 15th and it has different amounts which add up to what my refund will be. 570 is a date of March 9th and has zero for the amount. I requested this account transcript on March 9th.
I can tell you that many people have received these exact same two codes in the last couple of years. They are fairly generic codes used internally by the IRS that can mean a variety of different things. The bottom line, is that your return got reviewed manually by a person and that's what is causing the delay. Many times, nothing gets changed on your return.
Some of the reasons that you could see a TC 570 on transcripts
My 570 is because missing W-2 which my previous employer has sent twice and irs say they have not received anything yet or IRS has yet to process it guess departments don't communicate.
You do have two other courses of action.
