If there is no SCH D or 4979, then you didn't mark them as sold. You marked the assets as "removed for personal use". That's all one needs to do to stop depreciation on the asset(s).
Work through the rental again. About the 3rd screen in make sure you did "NOT" select the option for "I sold or disposed of this property in 2017".
Then work through each asset. You'll come to a screen that asks if you "Stopped using this asset in 2017". If you clicked YES then the next screen asks "Special Handling Required?" If you clicked YES again, then you indicated the asset was not sold, but was removed for personal use.
I guarantee you that one or both of the above are true if there's no depreciation on the asset *and* there is no SCH D or 4797 in the 2017 return.
To make the change, the ***FIRST*** thing you do is make a backup of the .tax2017 file as originally filed and accepted by the IRS. Then (and only then) will you elect the option to amend the 2017 tax return.
You *must* get the 2017 return amended before you can even start your 2018 return. Otherwise, the information imported from the 2017 return will be incorrect.
Also note than an amended return can not be e-filed. The IRS says so. You have to print it, sign it (both the 1040 and 1040X) and mail it to the IRS.
Finally, since it is past Oct 15th, 2019 you also have no choice but to print, sign and mail your 2018 return to the IRS.
*DO* *NOT* mail your amended 2017 return and your 2018 return in the same envelope. If you do, you will find yourself in a never-ending nightmare with the IRS from which you will never awaken.
