You should do exactly what the IRS is
requesting so that your return will be processed as quickly as possible. You'll need to mail it in.
You'll actually
start an amended return in TurboTax to create the Form 8962 that the IRS
needs. Please see the TurboTax FAQ
"The IRS is requesting
Form 8962 for 2018" for additional guidance. Note that there are different ways to do
this, based on whatever version of TurboTax you're using. They're shown in the three dropdowns near the
bottom of the FAQ.
