Hello @sherrilrflint ,
They won't show up if you do not specify the tax line in the manual JE that you have posted. It isn't enough to just enter the GST/HST payable account. You must tab over to the Sales Tax field and enter the correct code. For example, it can't distinguish whether this transaction is for a sale or a purchase. The tax code will distinguish that. See below:
This is just an example and maybe not a very good gone. But it shows how you have to direct which Line of the report your GST/HST entry should go to. Keep in mind, that you could have a GST/HST Payable CR amount that is also a Line 106 - if it is a credit or a reversal of a bill or expense. Same with the Line 103 - if you are recording a line to account for a credit you gave to a customer, then it would be a DR and still go to Line 103.
Hope this helps. Good luck!
