Just take it into the shop, but best practice would be putting a spacer between the pads anytime you are taking off a wheel to prevent this, but if this does happen I personally would just try and spread the pistons manually with a dedicated tool or even a tire lever and then spray down the pistons with some alcohol and wipe clean. In the case of opening the bleed port, you possibly did get some air in there. Again you could try and a minor bleed on that lever but frankly if this is your first hydraulic bike just take it into the shop especially if you can't reset the pistons
