It won't affect your 1099K, so relax, that isn't at issue here. Ebay has detailed transaction reports to support the numbers that the 1099k reports.
What the 1,373.58 is saying is that you have that much LISTED and SOLD. So it is the combination of the two things. Your sold items and the items you are still selling that are not yet sold.
Still it doesn't look accurate, but maybe it will correct itself in the coming days. It isn't a number that will hurt you in any way. But it is annoying it doesn't seem to be accurate.
