Toilet runs into bowl at the end of fill

[Skoot]

My upstairs toilet has started running into the bowl at the end of the fill.

It flushes ok and then fills ok, but towards the end of the fill (for around 10 to 15 seconds) water runs from the
tank into the bowl then it stops filling and all seems well.

I'm thinking it's probably something that needs to be cleaned or adjusted but I don't know what.

Any advice would be greatly received.

TIA, Skoot

Are the flushing mechanisms different in USA?

Please take a picture of your tank components and post them up in order to see what you have.

make sure the flapper that seals the hole to the tank in the fill tank, rubber is good and seated all the way., that flapper may need to be replaced

OK, I finally got round to taking the top off the cistern.
Water is flowing into the overflow and then into the toilet bowl for about 18 seconds after the level reaches the top.
I tried adjusting the black screw thing on the left hand side but it didn't make any difference. I can't see any way of raising the level of the overflow so I'm stuck.

Any suggestions, please?

I believe if you take that fill valve out of the tank it can be adjusted lowered and then lock it so it doesn't pop up

That’s a fluidmaster ballcock.

Look up how to adjust it. Or just replace it. It’s nothing special. They cost $8

I tried adjusting it, but it made no difference.

I've bought a replacement. I'll fit it tomorrow. They must be cheaper in USA, it cost me 25 bucks.
