Every 5th-gen CR-V sold with an automatic uses a continuously variable transmission, so forget everything you know about dropping a pan and changing a filter. There are two plugs: an 18 mm drain underneath and a fill plug on top of the case, and no dipstick anywhere. A drain and fill pulls roughly 2.6-3.0 quarts out of a system that holds around 6-7, which is why people who want the fluid genuinely fresh do two or three drains spaced a few hundred miles apart instead of one flush.
The thing people get wrong is fluid choice and order of operations. This CVT takes Honda HCF-2 and nothing else - DW-1, ATF Type 2.0 and aftermarket 'universal CVT' fluids cause shudder and belt wear. Second, crack the fill plug loose before you touch the drain plug. It is buried on top of the transaxle, it can be tight, and discovering that with an empty transmission ruins your weekend.

The 1.5L turbo and 2.4L K24 both use the same HCF-2 CVT, so the 18 mm drain plug, 17 mm fill plug and roughly 3 quart drain-and-fill volume apply to both. The 2020-2022 Hybrid uses a completely different two-motor e-CVT transaxle with its own fluid spec and capacity and a separate drain/fill location - confirm the fluid type and volume in the Hybrid service information before touching it. Access under the 1.5T is slightly tighter because of the turbo plumbing and heat shielding, so plan on extra extensions.

About 2.6 to 3.0 US quarts comes out on a level drain, against a total system capacity of roughly 6-7 quarts. Buy 3 quarts of HCF-2 for one service, or 9 if you plan three spaced drains for a near-complete exchange.
No. The HCF-2 CVT needs HCF-2's specific friction properties for the steel belt and pulleys. DW-1 or universal CVT fluid typically shows up as shudder from a stop within a few thousand miles and can permanently glaze the pulleys.
Honda's procedure uses a special dealer dipstick tool inserted into the fill port at a specified fluid temperature. For a DIY drain and fill, measure exactly what drained out and put the same volume of new fluid back with the car level - that is accurate enough.
Honda goes by the Maintenance Minder, which often lands around 25,000-30,000 miles for severe use and later for easy use. Many owners do a drain and fill every 30,000 miles, and sooner if the vehicle tows, sees stop-and-go traffic, or the fluid has gone dark.
