When you get everything sorted out, you may consider exporting the database to a CSV file. That way you can print the file out and have a physical copy of everything. Also, the CSV file can usually be imported into a new app saving you hours of doing it by hand. Obviously keep all those in a very secure place. Be sure to create a new CSV file periodically to reflect new entries.
I believe you can export your 2FA seeds in a lot of 2FA apps. Might do that as well and keep it secured with your CSV file. Those exported seeds can usually be imported into most 2FA apps as well.
