After you file

@mytaxstuff   Did you already file your original return and was it Accepted?  If you have not filed yet then do not amend.  Yes you always have to wait until the end of Feb or March to see if the brokers put out amended 1099 forms.  It is very common.  So if you have investments then don't file early each year.  I think you delete the first import and then import the new 1099.  In fact I wait to import until they put out any amended ones.
