Related to missing benefits

Hi everyone,

I filed my income tax return for this year with TurboTax. It was estimated by the TurboTax that I will receive some sort of money from the CRA as GST/HST benefits and other credits, but I received mail from CRA stating that I need to send some documents, so that they can calculate the exact benefit amount.

What should I do now? and I do not know where to submit the documents.
