During my e-file, turbotax realized that I was eligible for both stimulus checks ($1200 + $600). The $1800 in stimulus checks was added to my "federal refund". Will I receive this portion of my refund earlier?

If the IRS just needs to know that I am not in fact a dependent, then shouldn't the stimulus money be given to me before my tax returns are even looked at? I am not sure how long it will take them, but it is not a tax return. 

Sorry if this question is a bit confusing, but I could seriously use $1800 right now!
