1099-INT

I filed my return already. I put some interest income I received under "Less Common Income Section" under "Miscellaneous  Income" on my Tax Return.  I then later received a 1099-INT in the mail late. The income figures match what I filed under the above section.

Questions:

1.  Do I do a amended return and place the income under 1099-INT section and delete the income form the Miscellaneous Income section or do I just leave it the way it is? 

2. If I leave it the way it is, will this trigger an audit?  I am not sure how the IRS computers respond, if the money figures match or the section matches.
