I want to use soft tubing running up the back of my tank for my return line and am wondering how to implement the check valve into it, would I have to Frankenstein something together with spigot barb adapters?
Soft tubing return line and a check valve

Not at all. What return pump are you using does it have a threaded output? You want the check valve as close to the pump as possible.
I should as what's your goal with the check valve?
It will not prevent a flood long-term if your sump cannot handle the backflow volume during a power outage. A properly sized sump does not need a check valve on the return line.

the unit is a rio plus 3420 lph
That pump doesn't use hose barbs or threads. Kinda a poor design. What size is the output? Quick google search it doesn't even specify. Why did you choose that pump?

I didnt, its a 3/4 barb fitting and I got everything from someone who didnt want it anymore
What's the need for the check valve?
I would skip it and just run the 3/4" tubing without it. If your sump is sized properly it's not needed.

I use soft tubing on my return with a 3/4” ball valve spliced in.
It’s not a fail safe device, that’s really not needed with a proper size sump. It’s original purpose was to dial down the output for an ac return pump. You can also use it to prevent a back flow (convenient, but not necessary) if you need to disconnect your return pump for cleaning.

Do I need to cement the drain lines inside the tank to the bulkhead?

My flex tubing goes on a slip connector on the return pump and the bulkhead on the bottom glass also has a slip connector I use two hose clamps on the tank side to ensure water doesn’t leak and the connection is tight.

The proper use of a check valve in a vertical pumping situation is twofold.
1 - to prevent high velocity backflow from turning a pump armature backwards. This can damage equipment (power surge) or (in some cases) unscrew the impeller.
2 - to keep the system primed and prevent large power-on surges of water and air.
When check valves are use to prevent flooding, the flood will inevitably happen, as check valves leak or fail with almost 100% certainty.
If you don't need to use a check valve, then don't use one. If you need a check valve to prevent flooding, then you need to redesign the system to prevent flooding without it.

Inside the tank overflow no, do NOT glue them.
