Why was a 1040 sr form filed for my taxes? I’m not sure why I didn’t get the extra $1000 and now it’s saying I’m not eligible for a stimulus check. What do I do?

The Form 1040SR is used for people who are 65 or older, based on the date of birth you entered in My Info.  The difference between "regular" Form 1040 and 1040SR is the size of the print.  The calculations are done in exactly the same way, and the line numbers are the same.  What "extra" $1000 are you asking about?  There is no extra $1000 refund.  If you are 65 or older you have a higher standard deduction.

Your standard deduction lowers your taxable income.  It is not a refund. 

2019 Standard Deduction Amounts

Single $12,200   (+ $1650 65 or older)

Married Filing Separate  $12,200   (+ $1300 if 65 or older)

Married Filing Jointly $24,400   (+ $1300 for each spouse 65 or older)

Head of Household $18,350  (+ $1650 for 65 or older)

Look on line 9 of your 2019 Form 1040 to see your itemized/standard deduction amount
