I have my first sump and I need to add more water to it. How do I maintain salinity? My LFS water is 1.026 SG, but my main display is 1.024 SG. Do I dilute the jug with ro water until its 1.024? I'm overthinking this, I know but I want to make sure everything goes smoothly.

Yes just dilute it with ro water until you get to the value you want
Why isn’t your value 1.025?
Are you using a refractor?

You should probably try to raise your tank salinity to 1.025-1.026.
Im using a Hanna salinity monitor. I want it at 1.025 but I don’t want to increase it overnight.

How big is your tank? And how much water will you be adding? An increase from 1.024 to 1.025 is fine "overnight". But I suspect you'll be adding only a small percentage of the overall system volume, so using the 1.026 will probably be fine (pending the information I asked about above...)

First, 1.026 is what natural sea water measures. That should be your goal. I would not dilute what you are buying. I would add it "as is" a little at a time until you raise your display tank to the same level.
You did not mention what size tank you have, but based on the assumption that you are buying pre-made water, I am going to assume it is a small tank.
Do smaller water changes, say 5%, and use the store made water as it is for replacement. It wont take long to balance the system. then you won't have to worry about it.

If you are adding water due to evaporation, top off with RO water.
You can raise salinity easily and slowly by adding saltwater as top off water over the course of a few days with no worries.
Once at your target salinity start topping off with RO water again.
Remember. You have to know WHY you are adding water.

I drew a line in my sump, so when I do water changes or whatever, I know I need to fill the sump back up to that line.
Once the sump is filled up to the line, then the ATO keeps it at the same water level. The ATO pulls rodi water from a 5 gallon tank just beside the sump
