You could go up to MyAccount and select "Clear and start over".....that selection defaults to transferring in last year's empty forms.
BUT...that is probably unnecessary......since, sometime in February you would download your Mutual Fund Tax information from the Brokerage that handles those funds, and would likely create all new new forms in the import process anyhow.
But if you enjoy entering all that information manually, then the Clear and start over is what you would need.....it does delete any test $$ information from 2016 you may have input already, but that probably wasn't very accurate anyhow.
