What do I do if waiting on hold for 2024 taxes with no explanation, how do I insure if I use info I have I won’t mess up 2025 return?

Same story as many, filed 2024 last feb, got 570 in march, no update till October when I got 810. Contacted congressman, he contacted irs, told me there is nothing I need to do, and everything looks good. Beginning of last month I finally got 571 code, but still have the 810. I have spoke to people many times who just say wait, and verified there is nothing I need to verify to them, or no amendment needed. I have yet to get a reason as to why return is still being held, but I worry if when I file 2025 when asked about 2024 amounts that using the info that I have may cause issues for 2025 as well. Are we not supposed to be informed of why they are being held? It’s been over a year with absolutely no explanation, and no advice on if I can use the number for what I think my return should be, or if that will cause issues. My 570 finally went away, but still have 810, and no further updates. I need to file 2025, but need to assure the same situation doesn’t happen again.
