On which line of which 2017 tax form where I find depreciation amount taken was entered?

Depreciation is not entered on a Form 1040.

The amount of Asset deprecation is shown on your Schedule C if you are self employed.  Schedule E if you have rental or royalty property.  Schedule F if you have a farm.

Thank you. If you haven't taken depreciation in one of the previous years, can you include depreciation amount of prior year in to current year's depreciation?

[DoninGA]

Asset depreciation is reported on an annual basis on a tax return.  Only the asset deprecation for the current tax year can be reported on the current tax year tax return.

When the asset is sold or otherwise disposed of the Total Depreciation for the asset is recaptured from the time it was originally placed into service, whether or not the deprecation was ever reported on a tax return.

You can amend the prior return (2015-2018) to add it if it would make a difference.
