How can I change the cost basis of my money market account?

Question

The accounts balances are all correct except cost bases and gain. When I try to correct the cost basis the balances are in error. I have Quicken Premier 2019 on Windows 10.

Another way to track down cost basis problems for your money market fund would be:
-- Go to Investing > Portfolio and select the Value view or another that shows the Quote/Price column.
-- Group by Accounts.
-- For the problem account and fund, click the little Plus sign next to the fund name. This will show all the tax lots for the fund. For a money market fund, there should be a 1 in the Quote/Price column for each lot. Correct any transactions where this is not the case.
-- If you have Placeholders, you will see a * next to the cost basis and in the Gain/Loss column.

Perhaps you have Placeholders that are affecting the numbers. Go to Edit > Preferences > Investing Transactions and make sure Show hidden transactions is checked.

This should have worked, but the calculations must be wrong somehow!
