Get the paper copy of your 1099-DIV form,
Delete the one you imported.
Then enter all the 1099-DIV data manually...that should fix it.
No way to know what is blocking your fixing the values on the imported documents.
Don't take a picture.
Don't upload a PDF.
Just enter all the data manually.
.i.e <Change how I enter my form> and <Type it in myself>
