After you file

No by the 26th means no later than the 26... when has the irs ever deposited on day other than one stated on the irs site? 
they send out direct deposit once weekly it’s Wednesday of every week notice the 26 is Wednesday so why would they send out before. 
Keep in mind your bank may take 2-5 days to credit your account. Just like if you have direct deposit at work they send out Wednesday so you can be paid Friday
