If you’re sure you’ve measured everything properly, I’ve found the culprit to usually be impatience on the part of the cook. I’m guilty myself once in a while.
Your lemon curd has to reach 170 degrees for it to set properly. Use a thermometer to make sure.
I'd make sure you're cooking it to the cues specified in the recipe and chilling it thoroughly; if it doesn't have enough time to set, it'll be loose. If it's still loose after that, try adding a bit more cornstarch--I'd hesitate to add an extra yolk because it might interfere with the lemon flavor.

I make a lemon curd Babka- and a firmer curd will certainly be VERY helpful! Thanks. 🙂
