After you file

Yes. And much faster then the 4 to 6 weeks. Total time from filing was 3 months and a couple if days. I have not seen CP12 letter yet but I live abroad and mail takes a long time. I think it was about 2 weeks since knowing there was an adjustment. Tge 4 to 6 weeks did not seem to apply but it is the standard answer IRS gives. Nothing standard this year.
