I'll do all that I can to make this process as simple as possible for you.
At this time, you can export your list of transactions, sorted by whether they have attached receipts or not. Here's how:
At this time, each receipt will need to be printed one-by-one if you're using QuickBooks Self-Employed. Since you already have the transactions list filtered by attachments, you can click the arrow on the right to expose the transaction details, and click the Download icon next to the receipt.
Since QuickBooks Self-Employed and QuickBooks Online were created for two separate business entities, they do not integrate at this time. The following article has more information about this policy, as well as details on what can be exported: https://selfemployed.uservoice.com/knowledgebase/articles/453178-switch-to-another-version-of-quickb...
Please let me know if there is anything else I can do to lend a hand.
