To make Placeholders visible, go to Edit > Preferences > Investment Transactions and make sure the Show hidden transactions box is checked.
Placeholders will have a gray background in the account’s transaction list (register) even if they are not selected, and will have “Entry” in the Action column.
Placeholders compensate for missing or incorrect investing transactions by forcing Quicken’s share balance for a security to match a specified value. This is usually the share count downloaded from your financial institution (FI).
Because transactions are missing or incorrect, Quicken will not be able to compute the cost basis or performance for the affected securities. You will see asterisks in the Portfolio views for this data.
Placeholders also prevent new transactions like Div, Bought and Sold prior to the security’s Placeholder date from affecting the account’s cash balance. This shows up as N/A in the Cash Amt column of the transaction list. To allow the cash balance to change when entering missing transactions that affect the cash balance, you must first delete the Placeholder.

Always back up your data file before changing historical transactions.
