XX/XX/XXXX I submitted XXXX quarterly estimated tax checks to the IRS. XX/XX/XXXX when I submitted my tax return I was told that they had not received the XX/XX/XXXX check. The check was submitted to my bank ( credit union ) and paid to an account at a Wells Fargo bank. The IRS did not receive the payment and the endorsement on the back of the check does not match their endorsement procedures.
