UART register is not debugging to terminal

This is a UART transfer between two atmega328p controllers. I am trying to confirm that the data is being properly passed by printing a variable from the data struct on the receiving controller.

My terminal is not displaying any information. I can only confirm that the code is being reached from my LED calls, where I enable portB.

I am fairly sure my BAUD rate is correct (51 for 8mhz). Also confident the hardware is hooked up properly. Any recommendations on how to debug further to find the issue? I'm new to AVR development so perhaps it's obvious to someone else.

Transfer

typedef struct  {
  uint8_t data;
  uint8_t timestamp;

  return UDR0;
}

//Waits until buffer is empty
void writeChar(char data)
{
  while(!(UCSR0A & (1<<UDRE0)));
  UDR0 = data;
}

int main(void)
{
  DDRD |= 1 << PIND1;         //pin1 of portD as OUTPUT
  DDRD &= ~(1 << PIND0);      //pin0 of portD as INPUT
  PORTD |= 1 << PIND0;

  int UBBRValue = 51;                                 //Set BAUD
