After you file

if the 1040-x is showing the same info in column A and C is there anything in column B 

if nothing in B then you didn't properly enter your changes.

if there are amounts in Column B do they appear to be the changes you made.    while rare, its possible that some changes will not  change your taxes.  the only way to be sure is either to upgrade so a pro can review return or take your amended return to a outside pro.
