The MD Form 511 should be available for electronic filing at this time.  Please let me know if you continue to have difficulties electronically filing.  

As described in length in the thread in sjrcpa's response, the return is not available for paper filing/printing at this time.  Until approval to use the revised forms is received we are mandated by the State of Maryland to turn off the printing function of the form.  

I know it has been a difficult filing season and sincerely appreciate feedback/comments on the product.
