Hello. I can help. Can you post a sketch for me to look at?
Unfortunately, that violates prescriptive requirements for wood I joists, unless the notch occurs over top of the support. That abrupt change in geometry is a big problem for stress concentrations in a plywood or OSB web that is intended to carry shear only and not bending moment.
There isn't just shear at the section. There is also bending moment.
You will need a different framing configuration.
