Count jsonb column where data is LIKE a sting in PostgreSQL 12

I have data in a jsonb column that looks like this...

{ "1": { "Answer": "Incorrect:No" }, "2": { "Answer": "Correct:The troubleshooting steps are correct", "Comment": "Computer was not restarted." }, "3": { "Answer": "Correct:The actions taken were correct" }, "4": { "Answer": "Correct:Clear next steps were provided.", "Comment": "Followup on fixing this issue." } }

What I want to do is get a count by question (1-4) of how many records have start with "Incorrect". I have the following query...

SELECT Count(reviews) FROM reviews WHERE review->'1'->>'Answer' LIKE 'Incorrect:%'

This will give me a count for that one question but I don't want to have 4 queries if I can help it. I've tried...

SELECT 
Count(review->'1'->>'Answer' LIKE 'Incorrect:%') AS "Count1",
Count(review->'2'->>'Answer' LIKE 'Incorrect:%') AS "Count2"
FROM reviews;

But that counted all columns. Any ideas?
