I have spent way too much time trying to create a PO in QB Online Plus.  The error message I keep getting is that I need to "select an account for this transaction".  I have tried many different suggestions from the Community to fix it.  I then watched a Tutorial, and I see that there are two additional columns in the Tutorial that isn't in the version I am using..  and those columns are "Product/Service" and "SKU".  The first column I have is "Description".  I can see how that makes a difference.

How do I fix this please?
