I don’t have any experience building a wheel or straightening a wheel etc. I am not a bike mechanic after all as much I would like to think I am ha.
So for things like this I might bring the bike to a bike shop to give it a going over, once I get it ‘looking’ straight.
You can ping them and you’ll tell if the tension is all over by the sound (if your really tone deaf use a free guitar tuning app)… if it is then I’d just loosen them all and start again. Much easier than trying to fix a bad build (you could over tighten some accidentally).
It’s not hard but its a bit of practice ..I follow the ali clarkeson Youtube
I used to write a label with tighten/untighten to remind me. Now I’ve done a few I don’t need to… but it used to be confusing when you spin the wheel towards you. (Might just be me)
A drop of oil on each nipple as well once its loose.
Worst case you take them to the LBS so no worse than trying from half done.
