updated with my I485 at TSC

A few days ago, I asked if anyone knew about the time frame of getting fingerprint results in TSC. Today I checked my case on-line and it showed that we (each member of my family) had been mailed notices for additinal information on 7/7. Sounds to me they are working on our cases and the results of fingerprint have been received by them (?). We have had !140 approved in Feb, and had fingerprints in Mar. Anyone here knows more information about this kind of situation?
