One day at a Time, Laverne and Shirley, Mork and Mindy and tie with Happy Days

After the April 9th 1981 airing, the show ranked #18 tied with Happy Days

After the the April 16th 1981 airing, the show ranked #34th two spots above One day at a Time at #36

After the April 23rd 1981 airing, the show ranked #37th one spot above One day at Time at #38

And after the last airing on April 30th 1981, it finished #44 above Laverne and Shirley at #46 and Mork and Mindy at #38

The show did well the first week placing in the top 20. The drop off in week two is dramatic and that continues into week three and four. Obviously the audience did not like what they were seeing. I think the show got a fair shot, ideally it would have been better to have The Jeffersons as a lead-in but that series was a 9:30 show and doing very well in a stacked CBS Sunday line-up. The competition on Thursdays was soft, NBC featured the fading Buck Rogers series the first two weeks and a news show the final two weeks, while ABC was tag-teaming Bosom Buddies and Mork & Mindy, episodes one & three of Checking In were up against episodes Buddies (the third episode was up against a Bosom Buddies rerun), episodes two and four against Mork. Bosom Buddies was struggling in its first season and Mork and Mindy now in its third season was a sinking ship by this point in time.

I never saw Checking In but it seems like kind of a pedestrian concept for a Norman Lear show.

CBS started the show after the Jeffersons season ended but like you said it could have still aired on Sunday Night
