In order to access Sales Receipts, you have to go through Accounting>Sales Receipts, under Customers section. This will open a list of Sales receipts, be sure to open the ones you want to analyse.
Check if the Accounts and Analytic Account are correct, Post the Sales Receipt if still in Draft status. Otherwise there's also an option to Cancel Receipt if has been posted already and information is not correct.
Refer to the open sales receipt screenshot below for details.
