How to i retrieve all my stored info about mileage, receipts etc to print for taxes???

Hi there, 

Thanks for joining us in the Community. I'll be glad to help share more info and steer you in the right direction. QuickBooks is an easy-to-navigate program that makes it simple for you to keep track of your accounting. 

While there isn't a single place/folder that contains all the info you've mentioned above, QuickBooks still gives you the option to access your data. In order to access the mileage, click on Apps > Mileage > from here you'll be able to see and manage your mileage history. You can also access your receipts by clicking on Bookkeeping > Transactions > select Receipts. The same applies for your taxes, you can access your tax info by navigating on the Taxes from the left navigation menu. 

Give this a try and let me know how you make out. I'll be a message away in case you need anything else.
