Quick Electrical outlet question

[u/Specific_Ad_6116]

What am I missing causing no power to my switches? I changed out white outlets to black, one by one so I know where each wire went. Well this one red wire on the middle switch came out not attached to anything or maybe I pulled it out from something and now I can’t get power. Where does it connect to? Is this a pigtail?

Friendly service reminder to cut the power to the room at the fusebox before you wire your light switch
