Error Check Questions

I have received two errors when I ran the error check after completing my taxes. They are listed below. In past years when I received such errors it would take be to the form where the information must be entered but it didn't do it this time. When I entered the information for the mortgage it said if the acquisition date is blank on the 1098 to leave it blank. I'm not sure what to do about the second error. The second question is based on items that I donated to a local charity.

 

1. Moraqsdt has an invalid date.

2. Cost/adjusted basis must be entered.

 

Thanks!
