To clear the error, when it asks for the RMD for that year, enter a $1 more than the actual amount. Leave the amount actually withdrawn the same as it appears on the 1099-R. When it asks you on the next screen did you withdraw the additional $1 during the collection time period, click no. The taxes owed on less than a dollar will not change refund/balance amounts and no additional penalty will be added. The error will disappear.
