Can not find Permissions assigned to created roles in Oracle - oracle

Question

I logged in as SYSTEM in SQL dev and did this:
ALTER SESSION SET "_ORACLE_SCRIPT" = TRUE;
CREATE TABLE Attendance
(
ID INT ,
NAME NVARCHAR2(300),
CONSTRAINT IdPk PRIMARY KEY (ID)
);
CREATE ROLE DataEntry;
GRANT SELECT, INSERT, UPDATE ON Attendance TO DataEntry;
How to find the permissions assigned to the DataEntry role? I've researched for a while, but the answers found didn't work. For example:
select * from ROLE_ROLE_PRIVS;
select * from ROLE_TAB_PRIVS;
select * from ROLE_SYS_PRIVS;
These statements return many many roles such as: dba,sys,.... But i still can't find my 'DataEntry' role. Can someone explain this to me? Thanks alot.

If you created any objects connected as SYSTEM, you'd rather not do that. SYS and SYSTEM are special, don't mess up with them.
As of your question:
SQL> show user
USER is "SCOTT"
SQL> create role dataentry;
Role created.
SQL> grant select, insert, update on emp to dataentry;
Grant succeeded.
SQL> select * From role_tab_privs;
ROLE OWNER TABLE_NAME COLUMN_NAM PRIVILEGE GRA
---------- ---------- ---------- ---------- ---------- ---
DATAENTRY SCOTT EMP INSERT NO
DATAENTRY SCOTT EMP SELECT NO
DATAENTRY SCOTT EMP UPDATE NO
SQL>
If you wanted to do such a query connected as a privileged user, then it is dba_tab_privs:
SQL> show user
USER is "SYS"
SQL> select * From dba_tab_privs where owner = 'SCOTT';
GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE GRA HIE
------------ ---------- ---------- ---------- ---------- --- ---
MIKE SCOTT DEPT SCOTT DELETE YES NO
DATAENTRY SCOTT EMP SCOTT INSERT NO NO
DATAENTRY SCOTT EMP SCOTT SELECT NO NO
DATAENTRY SCOTT EMP SCOTT UPDATE NO NO
SQL>

Since you tagged SQLDev...open the View menu, select DBA.
Add your connection. Expand, go to Security, Select Roles, open your Role.
Observe the Object Privs panel.
SQL Developer gets the object privs for a roles using this SQL
SELECT privilege AS "Object Privilege"
, owner AS "Schema"
, table_name AS "Object"
FROM dba_tab_privs
WHERE grantee = :name -- DATAENTRY
ORDER BY 2
