If it's feeling too much like a chore, then stop actively TTC for a while. It puts a lot of pressure on and isn't nice, can make sex perfunctory and all about the endpoint, rather than relaxing and enjoying.
If your episiotomy scar is still sore, is it worth talking to the GP about getting something done? It shouldn't still be sore a year later, I'm pretty sure!
If you have the time to put TTC on hold, that would be my main recommendation - give both of you a break while you try and re-find the things you enjoyed about having sex.
