In Sept 2019 Quicken lost thousands of transactions in 2 credit card accounts. How to restore?
Preparing 2019 taxes this month (May 2020) and reviewing my past-year spending, to my alarm I see that in two credit card accounts that I have been using for years, the earliest transaction date is now in August 2019. Trickery from filtering and sorting has been ruled out, including by running itemized spending reports on these accounts including all dates. How did this happen and how can I recover my transactions from my backups?
In my backup software, I am able to look at every prior version of my QDF (Quicken) file, and I see that up to and including the .QDF file on August 29 2019, transactions both of these accounts go back many years. The next version of the QDF is from September 15 2019, and the transactions prior to August 2019 are missing in that file and in subsequent versions up to the current date. It appears that in either August 2019 or in September 2019, all transactions prior to September 2019 were removed. These accounts are both enabled for one-step update, but I would hope that this Quicken feature would not allow deletion of any records, let alone thousands. And another credit card account also using 1SU was not similarly stricken.
Assuming I am correct in concluding that the transactions are really gone from my current Quicken file, how can I restore the missing credit card transactions from the old versions? (So thankful for backups!) From the old Quicken file I have copied the deleted transactions to the clipboard with Edit/Transaction/Copy transaction(s), but when I open the new file and enter the credit card account the Edit/Transactions/Paste transaction(s) menu option is disabled. Quicken does not allow both Quicken files to be open at the same time. It will be very difficult for me to start with my Quicken file from August 2019 and rebuild it to the present time, and since I don't know how the transactions were deleted, I don't know how to prevent it from happening again.
Thanks for any help.
