Investment Account value in Net Worth field is not the same as current balance
I am using Quicken Deluxe 2016 and will soon have to upgrade to 2019. My laptop's OS is Windows 10. I closed an investment account 2 years ago and opened another one with the funds with another company. The old account is now showing up in my Hidden Accounts with the correct cash balance of zero but the Securities Value and Total Market Value are showing a large figure. How can I manually change those figures to zero to have the correct value? I have read similar questions in the forum but the answers are too complicated for me to follow. I just need to be able to change the 2 figures to zero. Thank you for your help.
