Adding entry validation could simplify this code a bit:
import time

def countdown(t: int):
if t < 0:
print("Not a valid entry")
return
while t > 0:
print(f"Time remaining: {t}")
time.sleep(1)
t -= 1
print("Timer reached 0")

It doesn't simplify code but what you're doing is right, there should be a validation for the input
