The clg joist dead load may not even be a factor either due to the small overall span. A beam only takes half the span. the other half is supported on the exterior walls. You can definetly get away with creating a "flitch plate" beam and eliminate the column all together. A flitch plate is the combination of conventional wooden lumber and steel plate sandwiched and thru bolted together. The splice joists overlap creating a solid beam mass. PM me ALL the dimensions of the garage including the overall span of the beam and clg joists above and the directions of each. I'll run a calculation and provide you with what size steel plate and how many additional 2x10 joists you'll need.
I have an architectural degree and its my day job if it helps reassure you... LOL.

Keep in mind that the double 2x10 is either butted to or on top of the garage header and with the extra weight added to the 2x10, the garage header may also have to be replaced. The beam is playing a part in supporting the ridge as you can see in the photos.
It looks like you are running 2x4 rafters at 16" o.c. with a 2x6 ridge. Its hard to tell much from the photos about the ceiling joists. Can you provide more detail about the ceiling joist. If the inside of garage picture is any indication that those are the ceiling joist I wouldn't plan on storing anything but aluminum cans up there.
I've been building homes since 1988 and have an engineer just a phone call away. If you get me photo, size, and span of garage door header along with the span of the double 2x10 I will give my engineer a call.
