Yes, the original and corrected amounts in 1040-X should be filled in with the Net Change column = 0.0. These columns should not be blank.
If any changes were entered before starting the amended return, they must be deleted. The Amend must be triggered before changes so that there is an Original amount in Column A.
To establish the correct Form 8582 and Schedule E, even though there are no monetary changes, an Amended return can be filed. However, the instructions do not specifically describe the scenario you are describing.
To be certain, see: Should I File an Amended Return?, to run through the IRS Interactive Tax Assistant.
For more information, see: Instructions for 2019 Form 1040-X.
