Tax topic 151

I filed my taxes on 1/27/2026 & was accepted on 1/28/2026. About 2 to 3 weeks later I received code 810 refund freeze on my transcript . I caught the id verification in my portal and waited on the notice . I verified on 2/18 once my notice arrived. Now I have code 766 credit to my account which is my whole refund amount. Everything has updated far as my transcript and WMR. WMR has tax topic 151 now with reference code 1242. What could be going on ? I went to a tax preparer also
