Just after takeoff we received a 'Bleed 1 Overpress' Caution msg. We waited until completing the after takeoff checklist and the autopilot was engaged before running the QRH procedure. The aircraft we were flying had Pack #1 deferred and this played a role in the mistake I made. The QRH procedure directed me to cycle the #1 Bleed button and I mistakenly cycled the #1 Pack button. After cycling the #1 Bleed button if the root caution msg is still present the procedure isolates the duct and requires a return to the nearest suitable airport.  We [advised ATC] and returned to ZZZ. All other checklists and procedures were completed [and the] remainder of the flight was uneventful.The primary cause was misreading the QRH procedure. I feel that had I cycled the Bleed 1 button we would have cleared the msg and we could have continued to our filed destination. I fixated on the existing MEL associated with the #1 pack and that led to not carefully reading the QRH. Also when I saw a diversion would be necessary if the msg persisted; I got ahead of myself by beginning to immediately think about how to handle the divert.Slow down and take time. Reread checklists and procedures. Also do [not] assume association of MELs to other caution msgs.
ERJ-175 First Officer reported returning to departure airport after receiving a 'Bleed 1 Overpress' caution message and incorrectly running the QRH.
