I apologize if I am not clear. 

Schedule L-- is based on the books. My financials had no depreciation on it when it was given to me. i mistakenly prepared the returns the way i got them. with no book depreciation. I forced Lacerte to show no book depreciation for the current year. 

The tax return has depreciation expense on it on page 1 of 1120s. The tax depreciation is properly recorded on the return. 

My concern is that schedule L's accumulated depreciation field is not correct. I should left it to default and not overridden it with "-1" under the "balance sheet misc" tab in lacerte. 

i understand i should have left it default and given the bookkeeper the deprec. entries. my question is should i amend these returns because of this book world error?
