I did an oil change. Thought the car took 4.4 quarts but it only takes 3.7 quarts. I poured in slightly under 4 quarts. The engine is a 1.5 in-line turbo (Honda Civic Si). It’s reading past the fill line slightly. How bad is it? Do I need to pour some out? What am I risking? What symptoms should I be looking for?

No. A little over the max fill line on the dipstick isnt going to hurt it. 1/8 of an inch overfilled or less is okay.
Usually if you don’t prefill the oil filter and only add what they say then sometimes it can be a little under. Its not a big deal.
Way too much and you risk damaging piston rings or flooding, but you really have to fill it to the point its spilling from the dipstick tube.

It’s fine.
Close enough!
Edit for a recommendation to OP: if you plan to change the oil in the same car for the foreseeable future – get a transparent plastic pitcher and add a fill line mark for the oil on the outside with nail polish, in your case 3.7 quarts. I do this with my car and makes for a no brainier oil change.
