Narrative:

Bleed 1 leak EICAS messagecaptain briefed me on the items he saw on the maintenance logbook during preflight. He specified that the previous crew had received a bleed 1 leak eicas message but the maintenance team couldn't replicate it. Captain mentioned that we should be aware of that same message to show up once we were inflight. I was pm on this leg up to ZZZ1. As we where climbing through FL220 to FL250 we received the EICAS message of bleed 1 leak. Captain called for the QRH. ATC instructed us to climb and maintain FL360; however captain asked me to request level off at FL250 while we ran the QRH. ATC told us to amend the altitude and advise when we were ready to continue climbing. I started performing the items mentioned in the QRH which there is one step (step 2) I missed (xbleed button pushout). Right after this message it asks if the message has extinghished and of course it was still present. We waited 3 minutes as stated in QRH but message was still there. We advised ATC and returned to ZZZ for further inspection. As we got to the gate captain and I started doing a debrief and saw that I had skipped a step in the QRH which might had a small chance of extinguishing the EICAS message. I have reviewed all these events and I believe task saturation was the primary issue in me as pm skipping this step. I should had asked the captain to take complete control of the communication with ATC and focus on the items mentioned in the QRH. We got task saturated as we expected we might had to return to ZZZ; deviations for weather and communications. During ongoing situations like these I will never forget that I had skipped a step previously. This will greatly help me to just focus on the items that the QRH is mentioning. Another thing is; I can always go back and read the QRH from the beginning; challenging myself to if the item was performed the appropriate way.
