Many do and state tax policies often are intertwined with federal tax policies but each state has its own set of laws and policies, some of which will need to be changed if they want to match those of the IRS. The difficulty for some states is going to be that they're already tapping into their rainy day funds pretty heavily and unlike the federal government can't run deficits, so they could run into cash flow issues when delaying tax payments. Of course that's bound to happen eventually anyway as sales tax revenue plummets and the number of people who can't pay other taxes rises.
Fortunately the vast majority of folks who didn't fuck with their withholdings will usually have a refund. So the state would actually get to hold onto your money for longer.
It does, however, kind of neutralize the point of the stimulus bill to some extent because this encourages you to hold off getting your refund if you are in the phase-out region (75k to 99k) and your income went up in 2019. If you don't file before they send the checks, they use your 2018 number, so it's potentially better to not file until the last minute. Which means a couple hundred bucks per person that isn't out there stimulating the economy. Again, assuming an average person that didn't fuck with their withholdings.
The threshold is outright bad policy but god forbid congressional republicans just pass a stimulus without trying to own the libs in the high-cost-of-living blue states.
The refunds usually come within a couple days of submitting, if it's electronic. Longer if it's paper. State is usually within a week or two for my state, but may be different for yours.

Wasn't it originally planned to go to everyone until Speaker Pelosi blocked it and said it must be means tested?
Usually the other way around. You used to be able to deduct state taxes from your federal. Trumped changed that so that state deductions no longer apply.
