I have an ITC adjustment to do on my tax return.It asks me to select an "adjustment account".What decides that choice, and what will the software do based on that choice?

Hi there, 

Making sure you're recording your ITC Adjustments in the correct accounts is a good exercise for preventing errors in your books. QuickBooks gives you the flexibility to choose which account you'd like to record the transaction under. Depending on the choice you select, certain accounts can be affected differently. 

I recommend contacting an accounting professional to get more info on this. If you're not in contact with one, I encourage you to search for one on our website using this link here. Doing this will help prevent any future discrepancies. Let me know if you have other questions. I'm here to help.
