Quackgrass is possible but can look very similar to other grasses.

I need a good high resolution photo of the grass and of clumps of the grass.
Aside from that you could take a sample to the Plant Disease Clinic, see my signature.

Quackgrass is hard to dig out because the rhizomes are hairy and even the slightest remnant can grow a new plant.
Tedious as it is, and as much as I dislike herbicides, you could apply glypohosate at per label instructions but paint it on the leaves with a 1/4 inch paint brush. Paint going backwards so that you do not get it on your pants' knees and drag it over good grass. https://extension.umn.edu/weeds/quackgrass

Quackgrass is very efficient at spreading via its underground roots (rhizomes) which spread horizontally 10-12 feet. Sorry.
