I am a family of 3 (myself, my husband, and my 11yr old son) my 2cd EIP was supposed to be $1800 I only received $900, why? That doesn't even add up for 2 of us.

depending on your income, your payment can be reduced or eliminated.

The stimulus check is an advance on a credit you can receive on your 2020 tax return.  If something went wrong or you did not get the stimulus check this year, you can get it when you file your 2020 return in early 2021—if you are eligible.It will end up on line 30 of your 2020 Form 1040.

At this point, we do not know yet what the new stimulus bill will mean in terms of changes to the 2020 Form 1040, software programming, software updates, etc., etc.  Do NOT be in a hurry to file your 2020 tax return until more is known.  It is never a good idea to file early, and it would be especially foolish to file an early 2020 return.

Update: I called the IRS to ask why it was 1/2 and they said where I had to file an injured spouse form on my taxes they deposited my 1/2 and are mailing my husband's 1/2. Thanks for your help.
