Is this big damage?

Before you jack it up to take any sag out check upstairs first with a level. If any reno's have been done over the years they they have corrected for the sag and if you jack it up everything will be out of wack upstairs and that can lead to a can of worms

Thanks for that advice. With having limited time when home yesterday, i took a full soda can and laid it on the kitchen floor to see if any low spots in the suspected area. No rolling of the can in any direction so it might be pretty level. When im back in town in a few days, i will check more thoroughly and also really pinpoint where the joist crack corresponds to in that kitchen ( might actually be under the cabinets. At the least, I don’t suspect significant sagging so I will probably follow your advice closely.

I don't see the electrical within a few feet of the knot. I would just sister a 3 ft piece on both sides with smaller size. Get some long bolts and go through all 3 after jacking up the crack area.

I'd go longer if there's room. 5 feet if he can. No need to mess with the wiring. Jack it up, sister both sides, and you're done.

Thanks again everyone for the input and ideas. I will be starting this fix after the predicted blizzard in.m next day or two.
After looking at the area better, there is no noticeable sag. I think I will use 3/4 inch plywood and sister both sides of the joist. I have about 4.5 feet free of obstruction to do this. The plywood is bc I have romex stapled along one side of the joist. There is some slack in the romex but I don’t think enough for a 2 inch wide sister joist.
I’ll report back soon

Another option can be found at joist repair.com. You will find a variety of metal plates and such to reinforce your floor joist.

That said you have been offered many suggestions any one of them will work.
