"if I try to amend my 2019 taxes, will I have the option of putting in my banking details"
No. you will not enter banking information if you amend your tax return because if you are getting a refund for an amended return, the IRS does not send you a direct deposit. They will only mail a check to the address on your tax return.
It is unclear whether you are thinking you need to amend to correct an actual mistake on your tax return or if you thought it would just be a strategy to get your refund. Do NOT send an amended return until your original return has been fully processed.
