Thank you for your reply.  I understood why it wasn't working in transactions to assign the payment account but I wasn't sure how to do it.  I think I figured it out which might be helpful to others who used personal money for start up costs and want to account for that.  Not sure if it is correct but it worked.  What I did:

Started a +New expense at the top

Added the expense.  For instance, Legal fees/services for filing my LLC say for 500

Added a second expense and used "Owners Investment" and put that expense at -500

I then attached the receipt where you can attach a file

In the Accounting page my "owner investment" went to +500 and my Legal fees went to -500

Again not sure if it is correct but it worked and it should be easily seen by an accountant at tax time
