Installing new switch - 3 black wires to 2 connections

Hello, I'm upgrading switches in a condo with newer Decora switches and plugs. I was working on the kitchen yesterday and ran into a roadblock. The garbage disposal wall switch has three black wires - 12 gauge wire on a 20 amp circuit. Two of the wires are backstabbed and one is curled around the bottom screw. (I'm not sure if this matters, but this garbage disposal switch is in a double outlet box with a plug that has six,12g wires - 2 red/2 white/2 black. I needed to buy upgraded backwire Decora switches to accommodate the additional wires in all of the kitchen plugs.)

The new switch only has two screws and will not accept a 12 gauge wire backstab. I'm aware of "pig tailing", and I was going to connect two of the wires together, but I'm unsure of which two wires I can safely connect together? I don't want to cause a fire. Is there a way for me to confirm which two wires can safely be pigtailed together? Thank you.

You connect together the two wires that were on the same terminal of the old switch. (Terminal being a screw and the associated backstab.)

Thank you for your reply. Just to confirm, I would pigtail the lower backstab and the wire wrapped around the lower screw and then connect the single wire to the lower screw? Lastly, I would take the upper backstab on the old switch and curl it around the upper screw on the new switch? Thank you.

Hello Ray, I want to thank you so much for replying to my post and confirming which two wires could be safely pigtailed together. I purchased the short piece of 12g wire today and completed the repair. Everything is in working order - no issues. Thanks again! I really appreciate your time. Have a great day!
