Modeling test: What to do about Goodwill & Amortization

For modeling tests, if you are given amortization on the income statement and there is a line on the balance sheet for goodwill & other intangible assets, are you supposed to subtract the amortization from the income statement? And then does this amortization go into the CFS? Or can you not use amortization from the I/S (like how you can’t use depreciation from the I/S - you’re supposed to take accumulated depreciation from the balance sheet)?
