Also be aware that you *CAN* file a joint return and you *CAN* claim the $24K standard deduction for the *ENTIRE* 2019 tax year - even if your spouse passed on Jan 1st of the tax year. The only difference is that on your joint return under the "My Info" section you will need to check the box to indicate that "this tax filer passed away during the tax year" for your spouse.
If you will be receiving a refund and elect direct deposit from the IRS, you should leave the joint account that refund is going to, open and active to make things easier for you. If you elect to receive a paper check then if that joint account is still open it should be no problem to deposit that paper check to that account with only your endorsement and a copy of the death certificate.
