I am about to apply for citizenship, marriage based, we did our tax me and my wife together last 3 years using H&R block and randomly I was checking our account and I found that’s we gave a balance due to pay for IRS, However we already paid and done our tax with a professional agency. I m pretty sure H&R block miscalculate our tax. My question is do I need to fix that first and wait to apply for citizenship or I just send my tax return for 3 years, Since fixing that tax thing may take time
