I was a dependent on the 2019 Taxes. I filed on my own for 2020. When I try to inquire about my stimulus for 2021 it says status not available. Any ideas on if I qualify or what the trouble may be? I

You are most likely eligible for a stimulus payment (see requirements below), but the timing of when you filed your 2020 tax return will determine whether the person who claimed you last year got the stimulus payment on your behalf or whether you will get it directly. 

The IRS will use available information to determine eligibility and issue the third payment to eligible people who:

• Filed a 2020 tax return.
• Filed a 2019 tax return if the 2020 return has not been submitted or processed yet.
• Did not file a 2020 or 2019 tax return but registered for the first Economic Impact Payment using the special Non-Filers portal last year.

Those eligible will automatically receive an Economic Impact Payment of up to $1,400 for individuals or $2,800 for married couples, plus $1,400 for each dependent. Unlike EIP1 and EIP2, families will get a payment for all their dependents claimed on a tax return, not just their qualifying children under 17. Normally, a taxpayer will qualify for the full amount if they have an adjusted gross income of up to $75,000 for singles and married persons filing a separate return, up to $112,500 for heads of household and up to $150,000 for married couples filing joint returns and surviving spouses. Payment amounts are reduced for filers with incomes above those levels.

Generally, if you are a U.S. citizen or U.S. resident alien, you are eligible for the full amount of the third Economic Impact Payment if you (and your spouse if filing a joint return) are not a dependent of another taxpayer and have a valid Social Security number (see exception when married filing jointly) and your adjusted gross income (AGI) on their tax return does not exceed:

• $150,000 if married and filing a joint return or if filing as a qualifying widow or widower
• $112,500 if filing as head of household or
• $75,000 for eligible individuals using any other filing statuses, such as single filers and married people filing separate returns.

Payments will be phased out – or reduced -- above those AGI amounts. This means taxpayers will not receive a third payment if their AGI exceeds:

• $160,000 if married and filing a joint return or if filing as a qualifying widow or widower
• $120,000 if filing as head of household or
• $80,000 for eligible individuals using other filing statuses, such as single filers and married people filing separate returns. 

short answer.

appears you are eligible but it's a timing issue related to when your 2020 tax return was processed by the IRS> 

They are only about half way complete with sending out stimulus checks

best case: you'll get it in a few weeks

worst case: you don't receive it and will have a 'recovery credit' of $1400 on next year's tax return.
