This is completely against the standard process. Once you know the overtime in time eval, creating it in IT2005 would be step back. You only use 2005 (and since ca year 2004 IT2002 instead), if you don't have clocktimes for the overtime.
If you have clocktimes overtime wagetypes are created based on T510s and schema. Then they go directly into payroll - or banktime.
Or your process requires approval. Then IT2007 is captured manually(!) as approval for the overtime to go through.
Strongly recommend to check basic PT process in training, or you are at risk of messing up a schema by learning detailed technical wizardrx, bot not understanding the fundamental principals.
