What happens to scheduled distributions during the black out period?

TIAA has confirmed that they will pre-pay any installments due from the beginning of the blackout period at TIAA until the end of the blackout period at Empower. So if you have a distribution scheduled with TIAA, you will likely receive that distribution earlier than usual. The regular schedule will resume after the blackout period ends with Empower initiating the distributions. 

Will the new recordkeeper affect our ability as retirees to count some or all of the retirement income as non-taxable housing allowance?
What will happen with my outstanding loan I have at TIAA?
