The error clearly points to data row 6 AddressLine3 column. I see that you are using SQL Server Import/Export Wizard. What you would need to do is restart the process and this time when you chose the source as your Flat File in 'Choose a Data Source' page of the wizard, go to Advanced tab on the left and for your AddressLine3 column, increase the width to say 500 and then proceed with the rest of the steps in the wizard.
