Amended Return

I received a corrected 1099 from our brokerage. I filed an amended return and am waiting for the federal government to process. The state processed it and gave me a small refund. Several days later I received a 2nd corrected 1099 from the brokerage and they adjusted ordinary and qualified dividends by $47.00 each. When I completed a new 1040x there was no tax due or no refund due. Do I need to file a 2nd amended return? Seems like its a waste of resources.
