Hello- I paid my 2018 tax using credit card from turbotax. How do I get my COVID stimulus payment check?

 Check the IRS website and update your bank information if necessary. 

 AGI is line 7 on your 2018 return and line 8B on your 2019 return.  Refund is line 21a of the 2019 tax return. and line 20a for 2018

Went to get my payment at irs site - entered needed info and bank info but response was info is incorrect per their records. Not so - I rechecked - even made sure low and high case letters correct.

@eekarts - additional hints: 

social security number must have the dashes included XXX-XX-XXXX

date must have leading zeros if necessary (e,.g. April is "04" not "4')

standardize your address :
