you do not enter anything on Line 30 - it is calculated automatically,
near the end of turbo tax, you'll be asked how much stimulus you actually received. Be sure to list the 1st and 2nd stimulus separately and accurately. The 14444 notice just stated how much you received; if you don't have it, it doesn't matter, just accurately enter what you received for the 2 stimulus payments.
then turbo tax will calculate Line 30.
if you still don't agree with what is on line 30, please post back details on why you think it's incorrect.
