Since you don't have to file a Federal tax return to the IRS with "only" SS income.
Then an Indiana tax return isn't required either.
.....then to get the "Unified Tax Credit for the Elderly" from Indiana, you have to file the SC-40.....except that SC-40 can only be printed out and mail-filed.
So make absolutely sure that ALL of your entries are complete in the Federal section...error checked again...Go thru the Indiana interview again, and error checked.......and if there is no Federal e-file again, select the file-by-mail option for the State section....print out the forms and see if the SC-40 is there to sign/date and mail in to Indiana. IF the SC-40 is not there, then it is available on the Indiana taxes website as a PDF file.

Note: Not exactly sure if the requirement is simply that a Federal e-file is not "required" (but can be done), or if it is Federal e-file is not allowed. There is a subtle difference between the two. You cannot e-file federal unless you have "some" other income, besides SS, that has been entered into your Federal tax return.
Even if you do have some other income, Indiana also has some other exemption $$ which result in an Indiana tax return not being required....and you would have to use the mail-in SC-40 again if those limits are not exceeded:
