Investors & landlords

Thank you. My situation si slightly different though. I need to amend taxes for 5 years, not 3: How do I amend taxes for years more than 3 years past? Also, all I need to do is include depreciation, and based on my past returns, it appears that it will not affect  a refund or additional payment. All this will affect is losses carry forward due to depreciation. (I understand that in cases when this depreciation affects Schedule E income to reduce, it is more challenging. But my Schedule E show up as minor losses for all previous years) In such a case, will it be more straightforward, and should I be able to amend all returns for past 5 years together?
