I suspect that you will have to remove the crypto detail from TurboTax Desktop and upload again the crypto detail into TurboTax Desktop.
In TurboTax Desktop, you can create a backup of your TurboTax Desktop tax return. I would create the backup at File / Save as and use it to make all of your changes. At least you will have the original tax return to revert to.
I do not know what kinds of uploads or downloads that you did to generate your TurboTax Online tax return. Most, but not all, of those processes are available in TurboTax Desktop.
Post here if you have further questions.
