I think I might have the answer. Per the "paper" copy, my JP Morgan Brokerage account did not receive a 1099-B. But a phantom 1099B was received through the import (TT shows a 1099B with blank amount for JP Morgan in the 1099B section). My theory is that whatever I input will never match because the data it is trying to match to is null, hence, putting me in an infinite loop.
