Fix duplicate Sales Tax GL Accounts

Upon setting up the Sales Tax in QBO my employer wanted to use the "exact" same GL # as I was given on the Trial Balance report that was provided.  I had not run QBO previously and came from a Sage background.  So I set up the GL in the same manor Sage would have handled Sales Tax, a GL account for Collected GST and another for the ITC's. So when it came time to file the first Qtr I ran the Taxable Sales Summary Report which showed the breakdown of all the different tax rates collected (sales, zero rated ...etc), this also showed the GST paid on purchases (ITC).  With that data confirmed I continued on with the filing and ran the GST Summary report where I noticed the ITC's were not showing on Line 106, so I thought strange but it allowed me to enter the amount that was reported previously and let me assign this to the GST account I had set up previously.   Thinking this was just how QBO sales tax process worked.  WRONG - this method is not reporting it to the balance sheet and I'm told by the accountant QBO handles the tax accrual in one GL account not 2 and it has pre-assigned account to handle this. Now I have a duplicate sales account and need to delete the one I set up and reconfigure QBO sales tax to preform how it was designed. I'm looking for insight and help on the "How to" on the proper steps to fix this error. TIA for any help that can be provided
