Do I have to file a amended return if the corrected 1099-Div didn't change my refund amount?

Hi All, I just received a corrected 1099 form for my brokerage account that added $14.33 to Box 5 of the Dividend page (Section 199A dividends). I already filed so I went into Turbotax and added the amount and it didn't change my refund or return. In this case, do I need to file a amended return? I've never done one on Turbotax and don't even know what it costs (I use the download version from costco). Thanks!
