Have you tried any of the products made for urine stains especially i.e., pet stain products ? I’ve had pretty good luck with it on carpet. It’s chemically formulated to neutralize the ammonia and whatever else comprises the smell.
We have a special needs son who wet the bed till 11 yrs. old and sometimes soaking the mattress from time to time with a half bottle (a little exaggerated) of the stuff was worth it. Cheaper than new furniture , better than the pee smell, esp. if the problem may recur and you can’t buy a new couch each week!
