Quicken connects to Fidelity and downloads only some of the transactions. The missing transactions are the Cash Clearing transactions. When a dividend happens Fidelity gets cash. Fidelity then clears the cash are purchases a money market ETF — either FRDXX or SPRXX depending on the account. Fidelity shows there transactions, but Quicken does not collect or transmit those entries.
