I try not to leave open parcels. I add the line first which I hope creates the new parcel and then delete or f-line trim the curve which should be an extraneous parcel. Of course this depends on which side of the curve you are on. Convex, concave?
Send me a file if you want.

Thanks John but I've already exploded the parcel and recreated it. I may try to recreate the situation as a learning exercise. The line would have been on the concave side putting the curve inside the parcel.
OK. What I did that worked (with help from johnm) was to trace over the arc, use the line and the new arc to create a new parcel then delete the 2 common sub-entities between the parcels, the arcs. The parcels will merge. I tried Parcel Union but it didn't work.
