Advice on how to file Amended Return

I filed about two weeks ago using actual paper because TT would not let me file electronically since I could not remember some piece of information from the prior year. 

 

Paper filing works for us since we never get a refund -- any money overpaid is applied to the next year taxes.

 

Based on an amended 1099 DIV we just received we now get a $350+ reduction in our amount owed. 

 

The question is how to file this amended return -- use paper again or try for the electronic approach?

 

This is not a tax question per se but instead I am looking for advice regarding the process.
